WASHING-MACHINE.

Specification of Letters Patent.-

Patented .m 13; 1909.

Application filed October 2, 1907. 'Serial No. 395,535.

To all whom it may concern:

Be it known that I, WALTER J. ZUILL, of' Syracuse, in the county ofOnondaga, in the.

State of New York, have invented new and useful Improvements inWashing-Machines, of which the following, taken in connection with theaccompanying drawings, is a full,

clear, and exact description.

This lnvcntlonrelates to certain improvements in washing machines of theclass set forth in the patent to Dodge & Zuill, No.

645,464, March 13, 1900 in which a Sheet metal tubis mounted upon asuitable tripod and adapted to receive a hollow conical sheet metalagitator or plunger capable of traversing the interior area of the tuband is also reciprocated vertically by the same actuating means and isalso adjustable vertically upon its actuating mechanism,

In or agitator, asleevc is journaled on one arm of a one-piece crank onthe frame or tub of the machine, and is connected by a parallel linkmotion and a suitable retracting spring to the su porting head for theplunger, one of the lin s being provided, with a suitable han- .Hebywhich the plunger may be-manipulated.

In my present invention I have sought to provide an eccentric clampingdevice for the plunger which is located between and protected more orless by the bars of the link motion and enables the plunger to beadjusted and clamped in any position thus permitting the use of atubular plunger without perforatin the same thereby reducing the weightof t 1e operating parts.

' Othorobjects and usos relatmg to specific parts. of the washingmachine will'behrought away. Fig. 2 is a top plan of the mechanism seenin Fig. 1 showing the greater ortion of the tub broken away. Fig. 3 is aongitudinal vertical sectional view through the plunger mechanism assoon in Fi ..1. Figs. 4 and 5. are enlarged detail sectional viewstaken-respectively on lines 4-4 and 5--5,

Fig. 1.

or to produce the desired vertical action and horizontal oscillatoryswing of the This washing machine comprises essentially a sheet metaltub 1, a hollow conical sheet metalplunger .2, a suitable actuatingmechanism for reciprocating the agitator vertically and movin ith0rizontally throughout substantially t e entire area of the interior ofthe tub. j

The tub '-1 is preferably mounted upon a suitable tripod consisting inthis instance of upright legs or channel lrons --3 and a. horizontallydisposed triangular frame 1 secured at its apexes to'the legs '-.3-'andextending under the bottom of the tub to form a support therefor, thechannel irons or legs -3-being extended upwardly along the sides of thetub equi-distant a art and are secured thereto by suitable. asteningmeans 'as bolts 5- which latter are usually arranged above the waterlineso as to avoid as far as practicable leakage in case the bolts are notsnugly fitted in the apertures through which they pass.

The plunger .-2-- preferably consists of a hollow conical sheet metalshell having a tubular stem -2D-, said plunger being movable verticallyand. horizontally by suitable mechanism hereinafter described and havingits stem adjustable vertically Within a U- shapesheetmetal hcad21-.ThisU-shape .head 21 is connected by a parallel lin-k motion to atubular sleeve -22 which is journaled upon one of the upright arms 23 ofa one-piece double crank. arm the other arm -25 of said crank beingjournaled in suitable bearings 26- and ;--27-. These bearin s arepreferably made in the form of brac ets secured in different hori-'zontal-planes one above the otherto one of the supporting legs 3- forthe tub 1, as best shown in Figs. 4 and5, each bracket being providedwith a channel and opposed ribs for receiving and embracing the adjacentportion of the leg --3 where it is held in position by suitable clampingbolts 5, the bracket ','26 being additionally secured to the tub by anadditional clamping bolt 29' and a reinforcing platen-28- which isinterposed between the inner heads of the bolts and adjacent inner faceof the tub.

The axes of the arms --22- and -25- of the. crank are parallel butareoll'set or spaced apart a sullicicnt distance to give the desired sweepor horizontal movement to the plunger -2- so that theplunger can bemoved by its operating mechanism "to trav erse practically the entirearea of the bottom of the tub.

The sleeve 22. and head 21 are disposed in parallel vertical planes andare connected at opposite sides of their axes by.

a lower pair of links--30? and an upper pair of oppositely disposedlinks 31-, thelinks 30 being pivoted at 32- to to the. sleeve '22-at oneside of its 'axisand are also pivoted at 33 to opposite sides of thehead 21',- said links 30 being: extended some distance beyond the pivot'33 wherethey-arexunited by rivets 'towhich latter elements they arepivoted sides of the c ampinp at 36-- and- 37 respectively therebyconstituting together with the links a parallel link motion connectingthe head 21, to the sleeve 22 to establish a parallel vertical motionfor the plunger 2. as the handle is operated vertically.

By disposing, the links of each set or pair at opposite sidesof a planedrawn through'the axes of thearms and stem 2(), I practically eliminateany possibility of torsional strains upon the: pivotal or, journalbearings of dillerent parts ofthe plpngeroperating mechanism and therebymaterial; increase the life of the machine.

The U-shape head -2] is closely iitted around three sides of the stem20- while the other side is engaged by a yielding elamping plate -4()-forming a part of the head and loosely secured thereto by the pivotalbolts and -=37; for he links -30' and -31-- rcs iectively, the iperturesin the l plate r---"40 being, slightly larger than therivcts which passtherethroiigh so as-to allow, aslight adjustment of the clamping head toandlrom the stem. 2() .,of the plunger whereby said clamping head may betightened and releascd' by the cam lever -43- v The liIiks -30'- and .31of each pair are spaced apart vertically and laterally and d between theplunger endof thc'links 8].,

is interposed a lever -43 which is prefei ably formed of sheet metal andis provided.

with opposite eccentric 'ears or bearings pivotally mounted upon the pin37 and edit ted to be brought into engagement with. t 10 plate -40- tospring the latterv into frictional holding engagement with the tubularstem 20 and to permit the lattefito be adjusted and clamped in anyvertical position. This eccentric lever '43' is therefore practicallyconcealed and rotected between the adjacent ends of the inks 31' which are spaced apart laterally a sufficient distance to permit the insertionof the hand or fingers of the operator for adjustment of thecam-leverinclamping or releasing the plunger inand fromits adjustedposition.

A coil spring -45 is interposed in a di-- agonal position between the lm(s -30 and I 31 of each set and has one end attached to the pivotal pin-36--of'the links '31.

while its other end is similarly attached toa separate pin 47 on thelower end of the head 21'- said spring being tensione'd to exert anupward. pull or lift upon the head 2land plunger 20 attached thereto sothat the agitator 2 is normally held in its extreme up position.

What I claim is:

1. In a washing machine, a arm mounted on the tub,"an upright sleevetub, a rock journal'ed on the ro'ck'arm, a pair of links I pivoted atone end to the u )per portion of thesleeve, a separate pair of inkspivoted at one end to the lower portion of the sleeve, a

clamping head pivoted to and between'the opposite ends of each pair oflinks, a plunger ad ustable vertically in the head, andia cam leverpivoted to and between the-lin-ksoflone-t pair and coacting with saidhead to clamp the plunger in its adjusted. position.

2.-In a washing machine, a tub, a rock arm .mountedon the tub, anupright sleeve journaled on'the rock arm, a pair of links pivoted at oneend to then iper portion of the sleeve, a separate pair of iinks pivotedat one end to the lower portion of the sleeve,' a clamping head ivotcdto and between the opposite ends 0 each pair of'links, a plungei;

adjustable vertically inthe head, and a'cam lever pivoted to aiulbetween the links of one
